Yes, because when driving you look out for small stuff all the time – kerbs, potholes, small children, stuff like that. What would be dangerous is to go up alongside a left-turning car at a junction, but you’d be daft to do that on any bike.
Lowracers aren’t any more or less invisible on the road than any other bike, is what I’m saying – and they have the advantage that all recumbents have of being unusual, so people actually take the time to look instead of ignoring you.
What bike did you try? All recumbents take a little time to adjust to – 15 minutes to get the basics, a couple of weeks or so to get really confident.
